      Makefile Whacking! Try to deal with the problem caused by the delay · 7590f9c5
      Leigh B. Stoller authored
      between when something is installed and when post-install runs. Short
      of a global lock (which we probably need anyway someday), my solution
      is this. In your makefiles, add these variables before the line that
      has the include of $(TESTBED_SRCDIR)/GNUmakerules:
      
      	SETUID_BIN_SCRIPTS   =
      	SETUID_SBIN_SCRIPTS  =
      
      I have added three new rules to GNUmakerules that look like this:
      
      	$(addprefix $(SBINDIR)/, $(SETUID_SBIN_SCRIPTS)): $(SBINDIR)/%: %
      		echo "Installing (setuid) $<"
      		-mkdir -p $(INSTALL_SBINDIR)
      		$(SUDO) $(INSTALL) -o root -m 4755 $< $@
      
      Yep, your eyes ain't lying to you; use sudo to run the target so that
      install does the right thing (which is that the old file is not
      replaced until the new one has the proper attributes on it).
      
      Note that post-install is still needed for the initial install, but
      should no longer be needed for day to day installs since all that other
      stuff post-install does is mkdir/chmod on directories.

      Major rework of the script interface to Emulab. Up to now we have been · 5ef8f70a
      Leigh B. Stoller authored
      supporting both a shell script driven interface, plus the newer XMLRPC
      interface. This change removes the script driven interface from boss,
      replacing it with just the XMLRPC interface. Since we like to maintain
      backwards compatability with interfaces we have advertised to users (and
      which we know are being used), I have implemented a script wrapper that
      exports the same interface, but which converts the operations into XMLRPC
      requests to the server. This wrapper is written in python and uses our
      locally grown xmlrpc-over-ssh library. Like the current "demonstation"
      client, you can take this wrapper to your machine that has python and ssh
      installed, and use it there; you do not need to use these services from
      just users.emulab.net. Other things to note:
      
      * The wrapper is a single python script that has a "class" for each wrapped
        script. Running the wrapper without any arguments will list all of the
        operations it supports. You can invoke the wrapper with the operation as
        its argument:
      
          {987} stoller$ script_wrapper.py swapexp --help
          swapexp -e pid,eid in|out
          swapexp pid eid in|out
          where:
               -w   - Wait for experiment to finish swapping
               -e   - Project and Experiment ID
               in   - Swap experiment in  (must currently be swapped out)
              out   - Swap experiment out (must currently be swapped in)
      
          Wrapper Options:
              --help      Display this help message
              --server    Set the server hostname
              --login     Set the login id (defaults to $USER)
              --debug     Turn on semi-useful debugging
      
         But more convenient is to create a set of symlinks so that you can just
         invoke the operation by its familiar scriptname. This is what I have
         done on users.emulab.net.
      
          {987} stoller$ /usr/tesbed/bin/swapexp --help
          swapexp -e pid,eid in|out
          swapexp pid eid in|out
      
      
      * For those of you talking directly to the RPC server from python, I have
        added a wrapper class so that you can issue requests to any of the
        modules from a single connection. Instead using /xmlrpc/modulename, you
        can use just /xmlrpc, and use method names of the form experiment.swapexp,
        node.reboot, etc.
      
        Tim this should be useful for the netlab client which I think opens up
        multiple ssh connections?
      
      * I have replaced the paperbag shell with a stripped down xmlrpcbag shell
        that is quite a bit simpler since we no longer allow access to anything
        but the RPC server. No interactive mode, no argument processing, no
        directory changing, etc. My main reason for reworking the bag is to make
        it easier to understand, maintain, and verify that it is secure. The new
        bag also logs all connections to syslog (something we should have done in
        the orginal). I also added some setrlimit calls (core, maxcpu). I also
        thought about niceing the server down, but that would put RPC users at a
        disadvantage relative to web interface users. When we switch the web
        interface to use the XMLRPC backend, we can add this (reniceing from the
        web server would be a pain cause of its scattered implementation).

      Cleanup Makefiles: · 297019fb
      Mike Hibler authored
      1. "make clean" will just remove stuff built in the process of a regular build
      2. "make distclean" will also clean out configure generated files.
      
      This is how it was always supposed to be, there was just some bitrot.

      Uniform syslog'ing. Change everything I could find to use a syslog facility · cc6d6fa7
      Mike Hibler authored
      as defined in the defs-* file (e.g. "TBLOGFACIL=local2").  The default is
      "local5" which is what we are setup to use so you shouldn't need to mess
      with your defs- file!
      
      perl scripts just get this value configured in when configure is run.
      C programs get the value in two ways.  For programs that are intimate with
      the testbed infrastructure, and include "config.h", they just get it from
      that file.  For programs that we sometimes use outside the Emulab build
      environment (e.g., frisbee, capture) and that don't include config.h,
      the value is set via a "-DLOG_TESTBED=..." in the GNUmakefile build line.
      If the value isn't set, it defaults to what it used to be (usually LOG_USER).
      
      Still to do: healthd, hmcd (whose build doesn't seem to be completely
      integrated) and plabdaemon.in (since its icky python :-)

      A bunch of lastlogin changes! The user and experiment information · 4658545e
      Leigh B. Stoller authored
      pages now show the lastlogin info that is gathered from sshd syslog
      reporting to users. That info is parsed by security/genlastlog.c, and
      entered into the DB in the nodeuidlastlogin and uidnodelastlogin
      tables. If not obvious from the names, for each user we want the last time
      they logged in anyplace, and for each node we want the last time anyone
      logged into it. The latter is obviously more useful for scheduling
      purposes. All of the various images have new /etc/syslog.conf files,
      and the 6.2 got new sshd_configs (all cvsup'ed with kill -HUP). There
      is an entry in boss:/etc/crontab and users:/etc/syslog.conf. All of
      this is decribed in greater detail in security/genlastlog.c.
